摘要：

We have successfully developed the world's first digital optical video disk camera capable of broadcast-quality recording The camera utilizes a phase-change optical disk with a memory capacity of 4.1 GB per side. The camera also possesses 20-minute recording per side at 25.8 Mbps using the signal format intraframe fixed length coding. Currently, electronic news gathering (ENG;) is done using a VTR, however, recorded information must be transferred to a hard disk drive for quick editing. Therefore, a total news system including tile camera will provide a good solution for the complete process, using the same optical medium from the stage ENG, editing, transmission, and archiving in both video versions of 525/59.94 and 625/50.
